Decaf Posted June 11, 2009 Report Share Posted June 11, 2009 1 6" aero might even be the most efficient since it has less surface area of port to create friction... its 28.27sqin... and might act more like 40-55sqin17.8 total length see... just listen to us and do 1 6" Quote Link to comment Share on other sites More sharing options...
FiBTLforlife Posted June 12, 2009 Report Share Posted June 12, 2009 well if i use one 6'' i need to make sure i got room. how much is the cut out and the total width of the flare on the port? this is a single cab truck so things are limited on space. i got 8'' depth and 15'' height to work with. i can let the port come out the box some but to an extent, mayble like 6'' or 10'' max outside the box. driver is a AQ15''HDC3 on a AQ3500d amp. i have already ordered the 4'' port lol and just got to the house today so if i can use the 4'' and would sound good ill use them. just not sure if the 6'' will work if the lengh is to long Quote 2 AQ 10'' HDC3 copper subs 1 3500d AQ amp 146.3db on TL with stock electrical in single cab truck at 32hz RESULT: 1st place at comp, 3rd overall out of 20 cars Link to comment Share on other sites More sharing options...
Derrick824 Posted June 12, 2009 Report Share Posted June 12, 2009 If you go with 4" use at least two. 6" ports have a 9.25" diameter flare. 4" ports have a 7.25" diameter flare. Quote Link to comment Share on other sites More sharing options...
FiBTLforlife Posted June 12, 2009 Report Share Posted June 12, 2009 ok im going to go with the 4'' tube since ive already ordered it and i believe the 6'' will hit the passenger seat head rest or may just be to big in general. i can get away with the 4' flare. Decaf along with me and Krannyman92 have come up with these measurements for the box. 3 4" port tubes at 26.5 total length for each tube. is this correct? i just want to double check before i order the other 2 ports Quote 2 AQ 10'' HDC3 copper subs 1 3500d AQ amp 146.3db on TL with stock electrical in single cab truck at 32hz RESULT: 1st place at comp, 3rd overall out of 20 cars Link to comment Share on other sites More sharing options...
